3 Claims. (Cl. 229-77) This invention is related to my co-pending application Ser. No. 514,325, filed June 9, 1955 for Fastener.

This invention relates to fasteners for expandible stationery folders and more particularly to the ribbon or tying element.

Expandable stationery folders or files are usually formed as an enlarged envelop with the open end having an enclosing flap. Envelopes of this type are necessarily provided with a string, ribbon or flexible strap to wrap around or partially around the envelop to hold the flap tightly closed. This string ribbon or flexible strap may be tied or may be fitted to a holding clasp. This invention is primarily concerned with a particular type of elastic ribbon and a particular means of easily renewing the old ribbon and easily inserting a new ribbon.

It is an object of this invention to provide a stationery folder in combination with a fastening element and elastic ribbon in which the elastic ribbon is provided with means at one end of said ribbon for easily inserting into said envelope in use for quick replacement of said ribbon.

A still further object of this invention is to provide a renewable elastic ribbon for a stationery folder in which the elastic ribbon is provided with a metal clip at one end thereof and in which the folder is provided with a slit aperture into which the metal clip of one end may be inserted to retain the elastic ribbon and permit fastening the ribbon to hold said folder closed.

A further object of this invention is to provide a renewable elastic ribbon in combination with a stationery folder and a fastening element in which the elastic ribbon is provided with a metal clip at one end thereof and in which the folder is provided with a slit aperture into which the metal clip and ribbon at one end may be inserted to retain the elastic ribbon and prevent it from being pulled out of said envelope and in which the other end of said ribbon is provided with a hook shaped fastener and said envelope is provided with a circular aperture to permit attaching the hook end of said elastic ribbon to said circular aperture.

A still further object of this invention is to provide a stationery folder in combination with a fastening element and a flat flexible ribbon in which the flexible ribbon is provided with means at one end of said ribbon that are easily inserted into said envelope to provide a positive anchoring of said end of said flexible ribbon.

A still further object of this invention is to provide a renewable flexible ribbon for a stationery folder in which the flexible ribbon is provided with a flat metal clip at one end thereof and in which the folder is provided with a slit aperture into which the metal clip and ribbon at one end may be inserted to retain the flexible ribbon and in which the other end of said ribbon is provided with a hook shaped fastener and said envelope is provided with a circular aperture in which a grommet is affixed to permit fastening the ribbon to hold said folder closed.

A further object of this invention is to provide a renewable flexible ribbon in combination with a stationery 2,847,155 Patented Aug. 12, 1958 a; folder and a fastening element in which the flexible ribbon is provided with a metal clip at one end thereof and in which the folder is provided with a slit aperture into which the metal clip of one end may be inserted to retain and anchor the flexible ribbon and in which the other end of said ribbon is provided with a hook shaped fastener and said envelope is provided with a circular aperture in which a grommet is aflixed to permit wrapping said ribbon around said envelope and attaching the opposite end of said flexible ribbon by means of said hook to said grommet aperture.

A still further object of this invention is to provide a renewable elastic ribbon in combination with a stationery folder and a fastening element in which the elastic ribbon is provided with a flat metal clip at one end thereof and in which the folder is provided with a slit aperture into which the flat metal clip and ribbon at one end may be inserted to anchor the elastic ribbon and in which the other end of said ribbon is provided with a hook shaped fastener and said envelope is provided with a circular aperture in which a grommet is aflixed to and in which the elastic ribbon is stretched to a greater length so the ribbon may be wrapped around the folder and permit the hook end to reach the grommet aperture and be hooked therein.

A further object of this invention is to provide a renewable binding element in the form of a cord for a stationery package in which the cord is provided with a metal clip at one end thereof and in which the package is provided with a slit aperture into which the metal clip and ribbon at one end may be inserted to retain and anchor the cord and permit tying or fastening the cord to hold said folder closed.

A still further object of this invention is to provide a renewable binding element in the form of a cord for a stationery folder in which the cord is provided with a flat metal clip at one end thereof and in which the folder-is provided with a slit aperture into which the flat metal clip and cord at one end may be inserted to retain and anchor the cord and in which the other end of said cord is provided with a hook shaped fastener and said envelope is provided with a circular aperture in which a grommet is aflixed to permit attaching the opposite end of said cord to said fastening element.

A still further object of this invention is to provide a renewable binding element in the form of a cord for a stationery folder in which the cord is provided with a flat metal clip at one end thereof and in which the folder is provided with a slit aperture into which the metal clip may be inserted to retain the cord and in which the other end of said cord is provided with a hook fastener and said envelope is provided with a circular aperture in which a grommet is aflixed to permit tying the cord to hold said folder closed.

Other objects of this invention may be apparent by reference to the detailed description and the accompanying drawings in which:

Fig. 1 is a perspective view of a closed stationery folder with a grommet mounted in said folder and a renewable ribbon attached to said folder,

Fig. 2 is a perspective view of the front of the envelope of Fig. 1 with the ribbon holding said folder closed,

Fig. 3 is a View of the renewable ribbon,

Fig. 4 is an enlarged partial View showing one end of the ribbon inserted into said envelope,

Fig. 5 is a cross sectional view taken on line 5-5 of Fig. 4,

Fig. 6 is an enlarged perspective view of the metal clip attached to one end of said ribbon.

Fig. 7 is an enlarged prospective view of the metal clip when it is anchored inside the wall of the folder and attached to one end of said ribbon,

tion of the folder showing the grommet mounted therein.

Referring to Figs. 1 and 2 there is illustrated a stationery folder or envelope 10 having one end 11 open and provided with an enclosing flap 12. A flat elastic ribbon 14 is provided as a separate article as illustrated in Fig. 3. Ribbon 14 is provided with a metal clip 13 at one end thereof and is provided with a hook shaped fastener 18 at the other end thereof. The metal clip 13 is shown slightly enlarged and in detail in Figs. 6 and 7 while the hook shaped fastener 18 is shown in detail in Fig. 8. The envelope 10 is provided with a slit shaped aperture 17 at a predetermined position adjacent to the bottom edge 16 of the folder. The aperture 17 is, in fact, a narrow slit large enough to permit forcing the metal clip 13 and the ribbon that is threaded through said clip being passed through the aperture while the clip retains the ribbon in a fiat relationship. However, when the clip has been forced through the aperture 17, the ribbon 14 may be pulled outward and when a pull is exerted on the clip it will take the position as illustrated in Fig. 7 lying flat against the wall of the folder and provide a good anchoring means for the ribbon 14. The clip 13 cannot be pulled through the aperture 17 with the ribbon. It is necessary to manipulate the clip through this aperture to mount the clip or to remove the clip. It is to be noted that the clip 13 fits snugly about the ribbon 14 and is positioned on the ribbon 14 by simply pressing clip 13 with sufficient pressure to give a good gripping relation on the ribbon 14. Referring to the opposite end of ribbon 14, Fig. 3, the hook fastener 18 is positioned at a predetermined position on ribbon 14 depending upon the sizes of the folder with which the ribbon is to be used. The fastener 18 is similarly pressed to provide a good gripping non-slip relationship with ribbon 14. Referring to Fig. 8, the hook fastener 18 is shown in side elevational view. It is apparent the ribbon 14 passes through portion 18A and is pressed into gripping relation by this portion. The hooked end 19 is, in fact, the fastening element. There is also provided a small apron or extension 21 whose purpose will be explained later. Referring to Figs. 1, 2 and 9, it is to be noted that a small aperture 22 is provided in the envelope 10 adjacent to the upper edge 20 of the folder 10. A metal grommet 23 is mounted in the aperture 22 to form a durable metal lip surrounding the aperture 22. It is to be noted in Fig. 2 that the ribbon 14 has been wrapped around the folder 10 and the hook shaped fastener 18 is aifixed by means of the hook 19 being passed through aperture 22 so that element 18 lies in a flat relationship with the outer surface of the folder. In order that the ribbon 14 may be saved from unnecessary Wear the extended apron 21 of metal prevents the ribbon 14 from making any contact with the edge of the grommet 23. In mounting the hook 19 or in removing the hook, there is always a metal to metal contact.

Referring again to Figs. 4, 5, 6, and 7, it is apparent that the mounting of the clip 13 through the slit 17 is a comparatively easy installation and as illustrated in Fig. it is apparent that when the clip has been inserted within the wall of the folder, any pull on the ribbon 14 will force the clip 13 into a flat relationship with the Wall of the folder, thus, either in the original installation of the ribbon 14 with its clip 13 and fastener 18 or in the replacement of a worn out ribbon it may be quickly and easily replaced. The removal of the worn out ribbon may be hastened by simply cutting the ribbon and throwing the two halves away. With this type of folder, the clip and fastener are spaced so that ribbon 14 is shorter than the distance from slit 17 of the folder around the folder to aperture 22, thus, ribbon 14 must be stretched and in a taut relationship will retain the flap 12 as il ustrated .4 in Fig. 2. The setting of fastener 18 with relation to clip 13 should be as close as permissible to insure a stretching of ribbon 14 and to allow for a change of the elasticity of the ribbon in use. Of course, when a ribbon has lost its elasticity, it is to be removed and a new ribbon inserted.

A still further feature of the hook fastener 18 is that instead of the flap 12 of the envelope 10 being in the position as illustrated in Fig. 2, it may also be turned backward and made to lie adjacent to the back cover and the ribbon 14 may be stretched over flap 12 in this position and the hook 18 can be hooked to any upper edge of the envelope to thus retain the envelope in an open position or hook 18 may be brought into the envelope and aflixed to the aperture 22.

Although ribbon 14 has been described as a fiat elastic ribbon, this invention shall include an elastic cord or binder of other shapes as long as the cord or binder is mounted in the same fashion to the clip 13 and fastener 18. This invention shall also include the use of a ribbon identical to 14 except that it shall have no elasticity. In this instance, the fastening element is mounted so that it is in approximately the exact position for the size of the folder or package that it is to be mounted about and, in this instance, the binding or flexibility of the package will be relied upon to permit the hook to be inserted. Although the preferred embodiment of this invention as illustrated in Figs. 1 and 2, illustrates a single ribbon 14 afiixed thereto, it is apparent that a plurality of ribbons or cords may be similarly used Without departing from the spirit of this invention. Although this invention has been illustrated in combination or associated with a folder for stationery etc., it is apparent that in place of folder 10, there may be a box or wrapping package embodying exactly the same features without departing from the spirit of this invention. It is also apparent that although a complete folder 10 has been illustrated, it is immaterial whether it be a complete folder or if it simply constitutes a pair of sides such as the face 15, Fig. l, and the opposite face as illustrated in Fig. 2 with any dimensions between these faces as long as element 14 is similarly used to be wrapped around the package and fastened in the same fashion as illustrated in the drawing without departing from the spirit of this invention and this invention shall be limited only by the appended claims.
